Rational Synthesis and Characterization of Robust Microporous Metal−Organic Frameworks with Base Functionality

Employing pyrimidine-containing ligands such as 1-(4-pyridyl)-2-(4-pyrimydyl)ethene (L) and 1-(4-pyridyl)-2-(3-methyl-4-pyridyl)ethene (L3) in assembly with Co(SCN)2 affords robust porous coordination polymers with uncoordinated nitrogen atoms on the channel walls.
